Who is Lee?

Lee appeared in Melbourne, Australia in the year 2000 at the exact moment the count-down for the new year ended. They claim to have no memory of anything that came before 00:00 01/01/2000, and may be an artifact of the Millenium Bug, or an accidental time traveler.

Lee met Eddie in a police lineup for a diamond heist they had both separately attempted. Unbeknownst to both of them at the time, but famous jewel thief, Tommy Two-bit had already stolen the diamond, and both had stolen fakes left by the previous thief. They laugh about it now, but secretly swear revenge on Two-bit.
